So far, so good for Kim Clijsters at Olympic debut

The Flemish tennis diva Kim Clijsters has enjoyed a successful Olympic debut, beating Italy's Roberta Vinci in straight sets at Wimbledon. Steve Darcis is also through to the last 32. Clijsters did not seem too much bothered by her muscle injury.

Kim Clijsters eyes a first ever Olympic medal after missing the previous Olympic Games in Beijing. Four years ago, she was in the middle of a two-year retirement, but she made a comeback afterwards.

The Belgian veteran, who is putting an end to her career after the US Open in September, swept past Vinci in one hour and one minute. She didn't seem bothered by her abdominal muscle injury and was relieved with the quick win. Clijsters next meets Spain's Carla Suarez Navarro who stunned Sam Stosur of Australia in three sets, 10-8 in the final set.

"It feels fantastic to be here at the Olympics, especially bearing in mind that I considered quitting a couple of times over the past 18 months. However, I didn't give up and I am glad about that now."

Still in the women's singles, Yanina Wickmayer is also through to the second round after downing Anabel Medina Garrigues of Spain 6-2, 4-6, 7-5 in a long battle that lasted over two hours.

Berdych stunned by Darcis

In the men's event, Steve Darcis also reached the second round, moving past the Czech Republic's Thomas Berdych 6-4, 6-4 in one hour and 26 minutes. The win against the 2010 Wimbledon finalist was a real boost for Darcis.

Berdych was the 6th seed at Wimbledon, but couldn't cope with Darcis' solid serving and groundstrokes. Berdych lost the Wimbledon final against Rafael Nadal two years ago. Darcis is only at 75 on the world rankings.

Olivier Rochus ousted by John Isner

Olivier Rochus was beaten by American John Isner, 7-6 (7/1) and 6-4. Isner is the world's number 11, while Rochus is just outside the top-100. Isner is also 40 centimetres taller than the small Belgian, which turned it into a kind of David and Goliath battle.
